Inspired by Peter Norvig's Lisp.py, I take two days and wrote a tiny but powerful lisp interpreter in JavaScript.
I improved arithmetic operator to support multiple parameter calculations, such as (add 1 2 3 4), and added some syntax sugars like let, let*, cond, else, and and or.
Now it could interpret a Y combinator!
install:
# npm install lisp.js
start:
$ lispjs
read code from files:
$ lispjs file1 file2 ...
Have fun!
